Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check fluid level.
If low, add the recommended power steering fluid (refer to owner's manual for specifications).
Replace the cap securely after filling.

3. Inspect and Replace Leaking Hoses

Identify any hoses showing signs of wear or leaks.
Use a socket set to disconnect the hoses from the power steering pump and rack.
Replace any damaged hoses with new ones, ensuring they are tightly secured.

4. Bleed the Power Steering System

With the engine running, turn the steering wheel from lock to lock several times to expel air.
Check the fluid level and add more fluid if necessary.
Repeat if needed until no air bubbles are visible in the reservoir.

5. Replace the Power Steering Pump (if necessary)

If noise persists after checking the fluid and hoses, the power steering pump may need replacement.
Remove the drive belt from the pump using a socket set.
Disconnect the pump from the power steering lines.
Install the new pump by reversing the removal steps and ensure all connections are tight.
